PC Engine Longplay  Blazing Lazers
Hudson-and-Compile-developed game. I found it while I was on a quest for many shmups.

Shmup = NO PLOT!
This game had a confusing power-up system at first. You have four main weapons (of course), and you can have one of four "enhancements": Shield, Multiples, Homing Missiles, or Firepower. Firepower makes whatever weapon you use moar awesome! (like the rotating shield weapon.)
Just going through the game while spamming the Firepower!Wave and Firepower!Rotating shield weapon while playing with NO SKILLS!
